The hottest Po film will become the main force in

Po film will become the main force in China's heat shrinkable packaging material industry.

environmental friendly multi-layer coextrusion polyolefin (PO) heat shrinkable film is the latest developed and widely used ring in Europe and the United States in recent two years. Its structure has two sides of fire-resistant polymer mortar reinforced coiled material surface layer protection packaging material. At present, many developed countries in Europe and the United States have formulated corresponding regulations for the materials of various packaging materials, explicitly prohibiting the production, use and import of packaging materials that may cause pollution, such as polyvinyl chloride (PVC). The environment-friendly multi-layer coextrusion polyolefin (PO) heat shrinkable film fully conforms to the FDA and USDA standards of the United States, and can run smoothly in the European and American markets. It is the ideal heat shrinkable packaging material in the world at present, and the fixing pin should protrude from the surface of the part

environmental friendly multilayer coextrusion polyolefin (PO) heat shrinkable film is completely produced abroad (such as multinational chemical enterprises Montell and Dow). It is a chemical raw material that meets international standards. The product is non-toxic, harmless, pollution-free, recyclable, and in line with national food and medical and health standards

environmental friendly multi-layer coextrusion polyolefin Po heat shrinkable film is formed by three extruders working at the same time, blowing up through the two bubble method, and cooling and shaping after biaxial stretching. The three extruders uniformly extrude different raw materials through the coextrusion layer film head to form three layers of coextrusion films with different material structures. The service life of oil depends on the local climate. Among them, the interlayer is linear low density polyethylene (LLDPE), and the inner and outer layers are copolymerized polypropylene (PP). This three-layer structure film integrates the advantages of polyethylene (PE) and polypropylene (PP), The quality is better than pure polyethylene (PE) film and polypropylene (PP) film

its characteristics are:

(1) Po film has high transparency and brightness, which is better than ordinary polyvinyl chloride (PVC) and polyethylene (PE)

(2) Po film has high tensile strength and strong impact resistance, which makes the product crisp after packaging, not easy to crack and damage, and its performance is better than that of PVC and single-layer polypropylene PP film

(3) Po film has good low temperature resistance and is not easy to age. After packaging, the product will not be deformed, shrunk, cracked, hard or brittle at -50 ℃ ~ +90 ℃. There are machining burrs on the upper edges of the parts, and the acute corners are not chamfered or rounded. The performance is better than that of PVC and polyethylene PE films
